A hiring manager needs an easy way to see what you're all about. Many candidates put a word cloud of technologies and software here but I've found that people are often pretty weak on many things included here. Word clouds don't have any context, either. The hiring manager has know way of knowing if this person knows just a little bit of a technology or if they do it all day, every day.

I call them "passions" because these are what I love to do at work. I'm confident about talking at length about any of them.
